IRONING-MACHIE Specification of Letters Patent.

Patented March 9, 1909.

Application led October 4, 1907. Serial No. 395,849.

To all whom it 'may concern.'

a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ironing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to improvements in ironing machines for ironing flat work such as bed sheets, table linen and the like, and the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims. i

Among the objects of my linvention is to provide a simple, inexpensive and eliicient ironing machine designed more particularly for household use.

As shown in the drawings Figure 1 is a top plan view, with parts broken away, of an ironing machine made in accordance with m invention. Fig. 2 is an end view thereof. Fig. 3 is a transverse section. Fig. 4 is a section taken on line 4 4 of Fig. 2. Fig. 5 is a fragmentary section taken on line 5 5 of Fig. 3.

The frame of the machine consists of two vertical end members 10, 10 and tie-rods 11 11 extending between and connecting said end members. The said machine is designed to rest upon a suitable horizontal support, as a table 12, and may be attached thereto by bolts or screws extending through bolt holes provided in said frame members, as shown in Fig.' 3.

13 designates a horizontal ironing shoe which extends between and is supported at its ends by the end members in the manner shown in Fig. 5, the ends ofthe shoe being recessed to t the upper margins of the end members. Said shoe is provided with an upwardly facing, smooth concave surface against which ,the articles to be ironed are pressed and over which they are advanced by means of a pressing roll 15 located above the ironing shoe, and movable toward and away therefrom. The shaft 16 of said roll is mounted at its ends in bearing sleeves 17 of roll supporting arms 18, 18, one at each end of the machine, which are pivoted at their forward ends by pivot pins or studs 19 to standards 20 rising from or constituting parts of Said endv members. The roll 15 is provided with a yielding cylindric face 21, made of felt or like material, as is common in machines of this type. The said roll is normally held elevated from the ironing shoe by a spring device, hereinafter to be described, and is pressed toward the shoe to press the work between the roll and shoe by means which will now be described.

25,25 designate roll actuating levers which are located one at each end: of the machine. Said levers are fixed tothe opposite ends of a horizontal rock-shaft 26 located below and .70

in front of the roll and extending between and rotatively mounted in suitable bearings in the end members of the frame. The levers extend forwardly and downwardly from said rock-shaft. 27, 27 designate links which are pivoted at their upper ends by bolts or pins 28 to the roll supporting arms y between the ends of the latter and are pivoted at their lower ends by other pivot bolts or pins 29 to said roll operating levers in front of said rock-shaft 26. 30 designates a treadle bar extending from side to side of the machine at the front end thereof, andit is connected at its ends with said levers 25 by links 31, 31 which are pivoted at their u per and lower ends to sai levers and trea e bar by pivot pins or bolts 32. Downward pressure on said treadle bar operates through said levers 25, the links 27 and the roll supporting arms to force the pressing roll against the work on the ironing shoet The table or support 12 is elevated a'distance above the floor and the machine is supported near one-margin thereof so that the roll operating levers, from which the treadle bar is suspended, may project beyond said suport. One of said roll operating levers 25 is provided with a short integral arm 34 extending downwardly and rearwardly therefrom. To the lower end of said arm is pivoted, by means of a pivot pin 35, one end of a rod 36 which extends rearwardly and has sliding engagement at its rear end with an apertured guide lug 37 formedon the adjacent end member of the frame. Surrounding said rod and interposed between the lugV 37 and a disk or washer 38, near the pivoted end of the rod, is a spiral expansively acting spring 39 which operates to swing the arm 34 of the adjacent roll actuating lever 25 forwardlyT and, thrpugh its connections with the roll supporting arms, to raise the roll from the ironing shoe. fixed attachment of the levers 25 to the rockshaft 26 the force of said sprin 39 is exerted on both ends of the rock-s aft to lift the roll through the links 27 The arm 34 of the roll operating lever against which the spring directly acts constitutes in eli'ect a crank of the rock-shaft, and when so considered may be located otherwise than shown. Said spring 39 thus serves to normally hold the roll raised from the shoe and the roll is forced toward the shoe by pressure applied to the treadle bar against the action of said spring. Said roll is rotated in a direction to advance the work between it and the shoe and pass said work over` the shoe for .the purpose of ironing the sa-me by mechamsm made as follows: Fixed to one end of the shaft 16 of said roll is a gear wheel40. 41 designates a, horizontal 'operating shaft `which extends between the end members of porting arms 18. Saidl operating shaft is provided at one end with a inion 43 which meshes with said gear whee 40 and is provided at its other 'end with acrank 44 by `which the shaft is rotated. 's herein shown said pinion 43 is formed directly on the shaft but may, obviously, be otherwise applied. By reason of the fact that the bearmg lugs 42 in which the operating shaft is rotatively mounted are carried by the roll supporting arms 18, it will be observed that y 6o bers.

the meshing engagement of the pinion with the gear isnot eifected in any manner by the raising and lowering of the pressing roll. In other words, both ofthe gears 40 and 43 are movable wlth the roll sup orting arms and are therefore raised and oweredl with the roll. f

50 designates a feed plate located in front of the roll over which the work is fed to the space between the ironing shoe and the roll.

lover which the workis discharged from the machine. .Said plate may also be made of sheet metal and 1s sup orted at its ends on lugs 53 formed integra w1th the end mem- VThe ironing shoe is heated through the medium of a burner pipe 55 which is located horizontally beneath the said shoe and is supported at its ends in the end members of By reason of the the frame. e The said burner pipe isslitted at its top for the egress of the products of a source supplying a burning gas. In order to confine the heat of the flame issuingv from the burner pipeto the space beneath the ironin shoe and to prevent the heat radiating forwardly and downwardly so as to unduly heat the support and the space in which the operator stands, I provide a shield 57 which is located in front of an`d below the burner pipe and extends between and is supported at its endson the end members of the frame. As herein shown, the said shield, which may be made of any suitable material, is provided at its upper ed e withv a grooved portion 58 which fits a' epending rib on the rear edge of the ironing shoe and it is held in lace by lugs 59 formed on the inner faces of ,said end members and engaging the side faces of the shield at the end marginal portions thereof. Likewise a suitable shield 60 is located beneath the discharge plate 52 of the machine and between the same and the burner pipe to prevent undue heating of said discharge plate. Said shield 60 is formed at its front ed e with a grooved portion 61 enga ing a epending rib on the rear margin o the ironing shoe and is suppoorted .by lu s 62, 62 extending inwardly from the en members of the' frame.

The pressing roll 15 isrnormally held elevated from the ironing shoe through the medium of the spring 39 acting through the medium ofthe arm 34, the rock-shaft, the links 27 and the roll supporting arms 18.

In the use of the machine the work is placed with its advance edge between the roll and the ironing shoe and the work is thereafter power app iedto the treadle bar 30. Thereafter the roll is turned @by manual power applied to, the crank 44, said roll being .turned in the direction indicated by the curved arrow in Fig. 3. The pressure of the.

ressed toward the shoe through roll on'the work operates'both to press the work a ains't the ironin surface and toad- Vance t, esame along t e surface so as to pro erly smooth and 1ron the same, and the wor Vis discharged from the said machine over the plate 52. -The said ironing shoe is kept heated to the roper temperature through the medium of) the ame issuing from the burner pipev and the arrangement of the shields operates to conne the heat i from said ame to the area where it most shoe.,

t will be evident that I have provided a machine which is exceedin 1y simple and eicient and-which may be uilt at a low cost, thus adaptipg it to household uses effectively and economically heats said ironrotatively mounted, means "actin arms, through the medium of which means' where a low price and easily operated machine is required. j
